I bought a Bose Cinemate GS series II like 6 months ago. The sound quality is awesome, but the fact that I can't adjust treble is bothersome. Usually movies sound like the dialogues come in at a low volume but then the explosions are amplified. There is no automatic adjustment between the highs and lows. Is there any hack to connect the system to a receiver? I've checked other forums and Bose says the system has a built in equalizer i.e. they don't want people screwing around with any settings than what they have chosen, which is not optimal for me. Please help!!
